Vintage women’s union suit circa 1920’s - 30’s labeled only “woolray”

As typical with vintage /antique clothing , there is no size or fabric content tag. I estimate this to be a women’s small- medium. It’s very soft and very stretchy. I am assuming it to be a wool/rayon blend. See photos for measurements.

This one piece garment is in really excellent condition especially considering it is likely almost 100 years old. Please note: there are some small spots - see photos. I gently washed this garment but did not attempt to scrub the little spots out of concern for the fabric.

Comes from a smoke free home.
